Oncological Outcomes From Cytoreductive Surgery and Heated Intraperitoneal Chemotherapy for Colorectal Cancer Peritoneal Metastases.

Cytoreductive surgery (CRS) is effective for colorectal cancer peritoneal metastases (CRPM) at increasing overall survival (OS) compared to systemic anticancer treatment (SACT) alone. The addition of Oxaliplatin heated intraperitoneal chemotherapy (HIPEC) has been shown in a randomized controlled trial to result in increased complications without significant OS benefit. This study evaluates outcomes for CRPM patients undergoing CRS+HIPEC with Oxaliplatin (Ox) 368mg/m (30 min), versus Mitomycin C (MMC) 35mg/m (90min).

Longitudinal Follow-Up of the Psychological Well-Being of Patients with Colorectal Cancer: Final Analysis of PICO-SM.

PICO-SM was a prospective longitudinal study investigating the psychological impact of the COVID-19 pandemic on patients with colorectal cancer treated in a large UK tertiary cancer centre. Here, we present the impact of the third wave of the pandemic (December 2021 to February 2022), when the Omicron variant became prevalent in the UK, and the complete longitudinal comparison across the entire duration of this study. Patients were invited to complete a questionnaire, including screening psychometric tools.

Preoperative chemotherapy response and survival in patients with colorectal cancer peritoneal metastases.

Treatment guidelines provided by PRODIGE-7 recommend perioperative systemic chemotherapy before cytoreductive surgery (CRS) for colorectal cancer peritoneal metastases (CRPM). Toxicity with multimodal treatment needs to be better defined. Chemotherapy response and impact on survival have not been reported.

Defining a role for systemic chemotherapy in local and advanced appendix adenocarcinoma.

Background: Appendix adenocarcinomas (AAs) are rare tumours that often present late, with a propensity for peritoneal metastases (PMs). This study aimed to evaluate outcomes of AA patients undergoing cytoreductive surgery (CRS) with curative intent and determine the role of systemic chemotherapy.

Materials And Methods: Data were collected from a prospective database and classified according to World Health Organization (WHO) 2019 classification.

Multisocietal European consensus on the terminology, diagnosis, and management of patients with synchronous colorectal cancer and liver metastases: an E-AHPBA consensus in partnership with ESSO, ESCP, ESGAR, and CIRSE.

Background: Contemporary management of patients with synchronous colorectal cancer and liver metastases is complex. The aim of this project was to provide a practical framework for care of patients with synchronous colorectal cancer and liver metastases, with a focus on terminology, diagnosis, and management.

Methods: This project was a multiorganizational, multidisciplinary consensus.

The Mental Health Burden of Patients with Colorectal Cancer Receiving Care during the COVID-19 Pandemic: Results of the PICO-SM Study.

The COVID-19 pandemic has resulted in unprecedented changes to the lives of patients with cancer. To evaluate the impact of the COVID-19 pandemic on the mental health and well-being of patients with colorectal cancer, we conducted a prospective longitudinal questionnaire study at a UK tertiary cancer centre. In total, 216 participants were included: mean age 65 years, 57% ( = 122) male, 92% ( = 198) of white ethnicity.

Modification to Systemic Anticancer Therapy at the Start of the COVID-19 Pandemic and its Overall Impact on Survival Outcomes in Patients with Colorectal Cancer.

Background: Since the beginning of the COVID-19 pandemic, multiple changes to the provision of cancer care has been introduced to maximize patient safety and protect staff. We aimed to identify factors influencing clinicians' decision on treatment modification during the initial phase of the pandemic, and to assess its impact on outcomes in patients with colorectal cancer.

Patients And Methods: Electronic records of patients seen in a large United Kingdom tertiary cancer center was reviewed.

Effect of oxaliplatin plus 5-fluorouracil or capecitabine on circulating and imaging biomarkers in patients with metastatic colorectal cancer: a prospective biomarker study.

Background: Patients with metastatic colorectal cancer are treated with cytotoxic chemotherapy supplemented by molecularly targeted therapies. There is a critical need to define biomarkers that can optimise the use of these therapies to maximise efficacy and avoid unnecessary toxicity. However, it is important to first define the changes in potential biomarkers following cytotoxic chemotherapy alone.

The Impact of Changes in Service Delivery in Patients With Colorectal Cancer During the Initial Phase of the COVID-19 Pandemic.

Background: The Coronavirus disease 2019 (COVID-19) pandemic has imposed significant changes in cancer service delivery resulting in increased anxiety and distress in both patients and clinicians. We aimed to investigate how these changes have been perceived by patients diagnosed with colorectal cancer and identify determinants of increased anxiety.

Patients And Methods: An anonymized 32-item survey in the specialized lower gastrointestinal cancer outpatient clinics at a tertiary cancer center in North West England between May 18 and July 1, 2020.

Review of metastatic colorectal cancer treatment pathways and early clinical experience of trifluridine/tipiracil in the UK named patient programme.

Background: The standard first- and second- line chemotherapy backbone regimens for metastatic colorectal cancer (mCRC) are 5-fluorouracil (5-FU)/capecitabine-based with addition of irinotecan or oxaliplatin. Until recently, evidence for optimal sequencing post second-line was sparse. Trifluridine/tipiracil (indicated for mCRC and gastric cancer after standard chemotherapies) was made available to UK patients via a named patient programme (NPP) before receiving marketing authorisation in Europe in 2016, allowing characterisation of UK treatment pathways, and evaluation of trifluridine/tipiracil in a UK non-trial population.

Biomarker concordance between primary colorectal cancer and its metastases.

Background: The use of biomarkers to target anti-EGFR treatments for metastatic colorectal cancer (CRC) is well-established, requiring molecular analysis of primary or metastatic biopsies. We aim to review concordance between primary CRC and its metastatic sites.

Methods: A systematic review and meta-analysis of all published studies (1991-2018) reporting on biomarker concordance between primary CRC and its metastatic site(s) was undertaken according to PRISMA guidelines using several medical databases.

Plasma Tie2 is a tumor vascular response biomarker for VEGF inhibitors in metastatic colorectal cancer.

Oncological use of anti-angiogenic VEGF inhibitors has been limited by the lack of informative biomarkers. Previously we reported circulating Tie2 as a vascular response biomarker for bevacizumab-treated ovarian cancer patients. Using advanced MRI and circulating biomarkers we have extended these findings in metastatic colorectal cancer (n = 70).

Rapid Analysis of Outcomes Using the Systemic Anti-Cancer Therapy (SACT) Dataset.

We audited the accuracy of the Systemic Anti-Cancer Therapy dataset as a resource for rapid analysis of outcomes for patients, in this example, receiving Cancer Drug Fund funded monoclonal antibodies to treat metastatic colorectal cancer. We concluded that the Systemic Anti-Cancer Therapy dataset is a potentially valuable resource for rapidly determining survival outcome for patients treated with chemotherapy.

Management of colorectal cancer presenting with synchronous liver metastases.

Up to a fifth of patients with colorectal cancer (CRC) present with synchronous hepatic metastases. In patients with CRC who present without intestinal obstruction or perforation and in whom comprehensive whole-body imaging confirms the absence of extrahepatic disease, evidence indicates a state of equipoise between several different management pathways, none of which has demonstrated superiority. Neoadjuvant systemic chemotherapy is advocated by current guidelines, but must be integrated with surgical management in order to remove the primary tumour and liver metastatic burden.

How many diseases are colorectal cancer?

The development of personalised therapy and mechanism-targeted agents in oncology mandates the identification of the patient populations most likely to benefit from therapy. This paper discusses the increasing evidence as to the heterogeneity of the group of diseases called colorectal cancer. Differences in the aetiology and epidemiology of proximal and distal cancers are reflected in different clinical behaviour, histopathology, and molecular characteristics of these tumours.

The neoadjuvant approach in the treatment of patients with advanced epithelial ovarian carcinoma.

Aims: Ovarian cancer has a very poor prognosis, with 5-year survival rates of 5-20% for advanced-stage disease. This work was designed to verify whether the neoadjuvant approach had an effect on survival in patients with advanced-stage ovarian cancer.

Materials And Methods: Patients with stage III or IV disease who received neoadjuvant platinum-based chemotherapy (group 1) were compared with a group of conventionally treated patients (group 2).

The interval from surgery to chemotherapy in the treatment of advanced epithelial ovarian carcinoma.

Background: To study the effect of the interval between surgery and the start of chemotherapy in the treatment of patients with advanced ovarian cancer.

Methods: We stratified patients according to the start of platinum-based chemotherapy in group 1 (within 4 weeks from surgery), group 2 (between 4 and 8 weeks) and group 3 (between 8 and 12 weeks).

Results: Three hundred and ninty-four stage III ovarian cancer patients were analysed.

Phase II trial of tamoxifen and goserelin in recurrent epithelial ovarian cancer.

Endocrine therapy is a recognised option in the treatment of chemo-resistant ovarian cancer. We conducted a nonrandomised phase II evaluation of combination endocrine therapy with tamoxifen and goserelin in patients with advanced ovarian cancer that had recurred following chemotherapy. In total, 26 patients entered the study, of which 17 had platinum-resistant disease.

Blockade of platelet-derived growth factor receptor-beta by CDP860, a humanized, PEGylated di-Fab', leads to fluid accumulation and is associated with increased tumor vascularized volume.

Purpose: CDP860 is an engineered Fab' fragment-polyethylene glycol conjugate, which binds to and blocks the activity of the beta-subunit of the platelet-derived growth factor receptor (PDGFR-beta). Studies in animals have suggested that PDGFR-beta inhibition reduces tumor interstitial fluid pressure, and thus increases the uptake of concomitantly administered drugs. The purpose of this study was to determine whether changes in tumor vascular parameters could be detected in humans, and to assess whether CDP860 would be likely to increase the uptake of a concurrently administered small molecule in future studies.
